Gears are an important component in modern industrial machinery that plays a role in transmitting power and movement between machine parts. This study aims to design and simulate straight gears using SolidWorks 2018 software by considering three different types of steel: AISI 1045 Steel (cold drawn), AISI 4130 Steel (annealed at 865°C), and AISI 4340 Steel (normalized). Evaluation was carried out on the strength, structural stability, and safety factors of each steel material used. The simulation results showed that the three types of steel were able to withstand the generated stress well. The maximum recorded Von Mises voltage is 294 MPa for AISI 1045 Steel, 304 MPa for AISI 4130 Steel, and 324 MPa for AISI 4340 Steel. The recorded maximum displacement of about 0.025 mm, indicating that the gear design has optimal stability during operation. The equivalent strain that occurs in all materials is also low, around 0.001, indicating a good ability to resist deformation when the load is applied. High safety factors are observed for all types of steel, reaching a maximum value of up to 42,521.7 for AISI 4340 Steel. Thus, this study concludes that the three types of steel evaluated are suitable for applications in straight gear design taking into account the dimensions and operational conditions that have been established, as well as contributing to the understanding of the mechanical behavior of gears and the importance of simulation in validating the design before physical production is carried out
